We would like to inform you that we have identified an issue in older versions of the product of our Windows business products.
ESET has identified that our kernel has a problem with verification of the timestamp of an already expired certificate (expired by 7th Feb 2020). This method fails and our modules in older, legacy versions, are declared as untrusted and therefore are not loaded. This mechanism ensures that no untrusted library is loaded.
As a result, the affected versions fail to load modules (Firewall, HIPS, Updated, Device Control, Web and Email protection) and are not functional, therefore the protection is not functional.
The following solutions are available:
1. If you have not restarted your computer with ESET Security product yet, make sure you have Update Module (version 1074.2) listed in Installed components. This module ensures protection and allows for subsequent upgrade to the latest version, which is required step to fully mitigate the situation.
Then, upgrade to the latest version:
2. If you have restarted your computer with ESET Security product v6.5, use the fixing tool and upgrade to the latest version if possible.
For ESET Security for Kerio 6.5, we are working on it and we will get it fixed as soon as possible.
If you are having any concerns or questions – or are unable to upgrade to the latest versions - do not hesitate to contact ESET Technical Support in your region.
